Today was the day to take the CORSAIR-II out of service, open it up, replace the dimming, flickering S-meter lamp with a BA9S 12 Volt LED replacement. While I had it open, I also wiped the pins of the display driver board and the logic boards with a Q-Tip dampened with CAIG DeoxIT Gold. Now it looks factory new again! 73 ES DX, Gary -- AB9M
